Stock 2013 subaru wrx possible boost cut?

[ScoobyPat]

Hey everyone first post on here so hoping I get some good responses I'm not new to forums I'm just new to the subaru community I've done my searching and can't find anything that relates to my problem.

I recently purchased a 2013 wrx. I've got about 1700 miles on it, last night we had a cold front come threw the same day I put my AEM intake on (witch is the only modification I have so far) I was driving the car around town and noticed when I go WOT in first gear when I go between 5k- redline, for a split sec I feel the car give out. All the other gears seem fine though its only 1st. Could this be some kind of boost cut/ fuel cut? Maybe the cold weather was to much for the car? It was about 50 degrees. Could the intake be the problem? All answers would be appreciated. I'm going to keep a eye on it and see if it goes away once we go back to normal temps (75-80 degrees).

But out of curiosity has anyone experienced this? If I need to explain Bette ill try my best just let me know.

Thanks everyone

Are you tuned for the intake?

I'm not, just installed it yesterday when we got the cold front. I was thinking a tune could possibly fix the issue I just feel like its weird that its only happening at the very end of 1st gear and no where else. And it's minimal but being a new car I want it to be running perfect lol

Frankly I would remove the intake at this point. Getting a tune just for the intake may not be as cost effective as you'd like, and in any case you don't have a tune yet but the car seems to need one (?).

Well, these cars don't have very smooth acceleration and it can sometimes feel like a stutter. But why you'd only be feeling it in 1st, I don't know. 50º really isn't cold, so your car should have no problem with that. Quite the opposite, I would think. My car feels fine in cold weather but runs like a slug when it hits 100º or more.

A tune can help smooth out the power band and, while there's some debate, the general consensus seems to be that you shouldn't run an intake without a tune. But that subject has been discussed here many times. So you might want do a search so you can make up your own mind. Maybe tune for the intake and see if anything changes.

Yea I've heard the same. I was planning on purchasing the COBB for the car anyways but this just gives me more of a reason to purchase it sooner. I guess since it only takes about 30 mins to swap out I'd be curious to see if it would do the same thing with the stock intake. Cause I've yet to drive it in this weather with the stock set up. We will see. I guess if anyone else has experienced this problem hopefully they chime I'm too. I might keep it on until it warms up a bit to see what happens. Because if it still exists then it could be nothing else but the intake

How many miles did you have on the car with the intake on it when this happened? Have you checked to make sure everything is fastened tightly/correctly and you don't have any air leaks?

Some people will tell you that you need a tune for the car with the intake, but I don't agree. Just that change shouldn't require a tune since the MAF is designed to account for exactly the type of change the intake introduces.

I couldn't have had many it has only been on the car for 2 days and I haven't gotten a chance to drive that much. And I'm pretty sure everything is tight and fastened, I took my time when I was putting it on to make sure everything was right.

Understand that purchasing an Cobb Accessport doesn't necessarily give you the proper tune for your intake. You should have a specific tune for your specific intake. If I were you I would take the intake off for now until you have the proper tune to use it.

I would suspect what you are experiencing is related to the intake without the proper tune...but just my opinion - I know others disagree. My main reason for posting was related to your comment about getting an AP to remedy the problem.
